Troubleshooting  
1. If the green LED is not on:  
a. Is the receiver correctly positioned in the slot? Are the screws tightened?  
b. Is the display turned on?  
2. If the LED is on, but there is no picture:  
a. Have you selected "Option" as input?  
b. Although it is unlikely, please check to see if the dip switches in the back of the unit (behind the black 60-pin connector) are  
in the correct position. The dipswitches on the unit must be set as follows:  
Position  
State  
1
2
3
4
Off Off On On  
3. If the picture is out of focus:  
a. Has the correct resolution been set?  
- NEC MultiSync® LCD4020, LCD4620: 1360 x 768  
- NEC M40, M46 and MultiSync LDC5220, LCD6520, L&P: 1920 x 1080  
b. The display has possibly been set up for a different size. Press the “Size“ button on the remote control until “standard“ is  
displayed in green in the top right-hand side of the screen.  
c. Has the unit been tuned properly? [See “Operating and Maintaining Instructions / Tuning]
